What is Synchronous and Asynchronous in Salesforce.
Apex can be executed
synchronously or asynchronously.
Synchronous:
In a Synchronous call, the thread will wait until it completes its tasks before proceeding to next. In a Synchronous call, the code runs in single thread.
Example:
Trigger
Controller Extension
Custom Controller

Asynchronous:
In a Asynchronous call, the thread will not wait until it completes its tasks before proceeding to next. Instead it proceeds to next leaving it run in separate thread. In a Asynchronous call, the code runs in multiple threads which helps to do many tasks as background jobs.
Example:
Batch
@future Annotation
